PLOW.

SPECIFICATION forming part. of Letters Patent No. 354,215, datedDecember 14, 1886.

(No model.)

To all whom, it 12mg/ concern:

Be it known that l, JOHN PENTREATH, a citizen ot' the United States,residing at Yonkers, in the county of Westchester and State ofNew York,have invented certain new and useful Improvements in Flows, of which thefollowing is a specification.

` The object ol' my invention is durability and strength in theconstruction and relation of the several parts, especially the beam,standard, moldboard, and landsidc, also,the Vertical adjustment of thehandles. I. attain these 0bjects by the mechanism illustrated in theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a perspective View of a plow in which my improvements areembodied, all the parts being in proper relation to each other, themold-board being shown by dotted lines. Fig. 2 is a top or plan view ofthe same. Fig. 3 is a horizontal section of the standard of the plow anda top view of the mold-board as braced by a projecting wing of thestandard and a brace rod or bar, the section being at line m x ofFig. 1. Fig. 4t is a vertical elevation of Fig. l, taken at the rear ofthe plow, a part of the moldboard and handles being removed. Fig. 5 is avertical side view of a plow, and shows two positions in which theplow-handles may be placed or adjusted to by the adj nsting mechanism,hereinafter set forth.

Fig. 6 is a rear vertical View of the standard, blocks, andplow-handles, the handles being in section, and show the corrugations ofthe standards and blocks interlocked. Fig. Sis a top view of the rearprojection of the standard, (removed from the standard,) the two blocks,and the bolt, and show the series of corrugat-ions on the standardprojecting above the faces thereof and the corrugations on the blocksbelow their bearing-faces. Fig. 7 is a detail of the rear of thestandard, showing the series of corrugations on one face and a verti calslot. Fig.. 9 is a front View of the face of one of the blocks whichbears against the standard. and shows its series of corrugations, also,two bolt-holes.

Similar letters of reference refer to similar parts throughout theviews.

A. is the plow-standard curved forward at the front so as to give alarge bearingsurface for the attachment of the beam and itsre-enforcement.` .At the rear it has a short wide projection, A, whichis bent to the right to bein the line of draft of the beam. The lateralfaces K of this projection or head are divided into two parts separatedby the vertical slot ai. (See Fig. S.) The irst part consists of aseries of short longitudinal eorrugations, m, which project above theother or second part, which isa flat bearing.

a a are two metal blocksplaced one on each side of the projection A:Said blocks flare toward the rear, and have top and bottom lateralprojecting flanges, 6*, which receive and securely clasp the lower endsof the plowhan dles. The inner faces of these blocks a' ce are (like thehead Ajdivided into two parts,thefrst part being a series of shortlongitudinal corrugations, m, whichare sunk below the other or secondpart, which is a fiat bearing-surface, S',

these two parts having the bolt-hole e2 be tween them, the corrugationsm corresponding to and receiving the corrugations m ofthe head A, andthe bearing-face S of said blocks corresponds to and bears upon thebearing- Vface S of the head A when the said parts are in properadjustment the one to the other.

e is a bolt which 'passes through the points of the handles, the lowerends of the blocks, and the standards, and binds all these partstogether, and also acts as a pivot on which the handles and blocks turn.

e2 is a bolt which passes through the handles and blocks at their rearor wide ends,and through the slot a of the standard projection A', andsecures these part-s together, the corrugations m and m meshing intoeach other and are so held by this bolt. It will be seen that when thebinding-bolts e e2 are screwed up the bearing-faces s and s of the headA and the blocks receive the lateral pressure and protect thecorrugations from being broken, and that the corrugations act to holdthe hanfurther, it will be seen that by slightly unscrewing the nuts ofthese two bolts thecorrugations m m will separate and the handles canthen be moved up to the position shown by the lines in Fig. 5, or downto that shown by dles to the desired vertical adjustment; and, 95

IOO

the dotted lines in the same figure, or adjusted to any other heightbetween these two points, as may be desired.

a is a Wing which projects from the right side of the standard A. Itsouter edge is of the contour of the mold-board which it snpports. On itsunder side it connects with the body ofthe ploW. (See Figs. 3 and 4.)

C is a steel landside provided with a shoe, C2, made of hard cast-ironin the shape of an inverted T. Itis several inches long, like a Trail,and its stem is placed along the inside of the landside to which itbolts. Its cross part on one side of the stem extends under the landsideat its rear end and rests or bears on the ground and receives all theWear which would otherwise fall npontheheel of thelandside. (See Figs. land 4.)

B is a brace rod or bar bolted to the inside of the standard A, a littleto the rear of and below the Wing d. lt extends transversely to theinside of the moldboard, to which it is bolted, and serves as a brace.

D is the plo\v-beam. It is constructed of steel7 that portion ot" itwhich connects to the standard being curved to correspond thereto, andthat part which extends in front of the standard is curved, as shown inFigs. 1 and 5. It is placed on the right side of the standard A, infrontof thelateral bend of the rcarstnndard projection, A',

D is a re-ent'orcing piece tothe beam D. At its rear it is curved tocorrespond to the form ofthe standard A, on the left side of whichit isplaced and parallel to thebeam D, the beam and its re-enforcement beingfirmly bolted to the standard by the bolts d d, as shoWnin Fig. l. Thepiece D extends beyond the front of the standard, and at about eightinches therefrom it is bent over a short metal block, d2, which is ofthe same thickness as the standard, to the rights@ as to bring its rightside or face into contact or bearing with the left side or face of thebeam D, to Whichit is firmly secured by the bolts d3 d A space ormortise, E, is thus formed betweenthe rear of block d2 and the front ofthe standard, which is used for the attachment of a jointer or anysimilar implement.

It will bc seen that by the construction of the plow as herein describedit is very durable, and that the beam, mold-board, and landside cannotbe broken by use or any ordinary accident, and are lighter than wood;also, that the metal blocks give a firm support to the handles by meansof their flanges, these blocks and the handles being all secured to eachother by the bolts e e2, and move With each other as one piece when thehandles are being adjusted up or down, as in practice it is notnecessary to withdraw the bolt e2, but only to loosen the nut enough topermitthe disengagement of the corrugations m and m and to slightlyloosen the nut on bolt e. The handles can then be moved tothe desiredadjustment, as the bolt e will move freely in the slot a2.

I claim- The plow-stand ard A, having the corrugated head A', and thecurved slot a, in combination with the blocks a', having outer anges,c4, and inner corrngations, m', the plow-handles, and the bolts e e2,substantially as shown and described.
